Grieving Miley pays tearful tribute to dead dog

She has been left devastated by the death of her beloved dog Floyd, a two-year-old Alaskan Klee Kai who was allegedly killed by a coyote.

And Miley Cyrus is taking her grief public, bringing a huge inflatable likeness of her pet on stage with her for an emotional and tearful performance in Brooklyn on Saturday, which saw her get on her knees as she sang to his memory.

Wearing just a bra, underwear and black and white furry chaps, Miley appeared inconsolable in a video posted by blogger Perez Hilton on his Instagram page.

The emotional performance comes after the superstar singer spent most of Friday night and well into the early hours of Saturday on Twitter agonising about her dog's death.

The 21-year-old spent a terrible night wrestling with Floyd's death and the advent of the new pup in her life, posting a cute snap of Moonie playing in one of her bags with the sad message: "So torn. I love having little Moonie cuddle w me and Mary Jane but just don't know if I'm ready to love again."

It followed a slew of increasingly more distraught messages peppered with tearful emoticons that Miley shared with her 17.7 million followers overnight.

At 3.40am the agonised star wrote:

?????? I wanna sleep but all I can do is cry ?????? I never wanna go home to a house where Floyd isnt running & playing ?? how do I get thru this??
